Application led May 12, 1919. Serial No. 296,562.

To all whom it may concern Be it known that I, Pmur HENRY JOHN- soN, asubject of the King of Great Britain, residing at St. Barnabas ham,Kent, England, have invented new and useful Improvements in Means ofSuspension of Vehicles, of which the following is a specification.

This invention relates to improved means of suspension of vehicles andespecially vehicles of the endless track type or those having anarticulated track or independent track shoes, but it is also applicableto vehicles such as railway vehicles in which the axles are guided byhorn plates.`

The object of the invention is to provide an effective suspension for avariety of types of vehicles (whether designed to run on rails, roads oracross open country) which will absorb shock caused b y obstacles,undulations Orirregularities of the surface traveled over, anddistribute by compensation the load due to the weight of' the vehicleover the various points of support.

In this specification the word rope is usedto describe any fiexibleconnection.

According to this invention a plurality of pulleys is mounted in a planeat intervals along the vehicle and a plurality of other pulleys isarranged alternately to the first set, and a rope is passed under thepulleys of one set and over the pulleys of the other set alternately.The ro e ma be secured to the vehicle or may be en less passing aroundthe vehicle and'sprin may be provided to increase the elasticity of thesystem and diminish shock to the rope.

One set of pulleys ma be carried on bogies having small WheellsI orrollers running on an endless track, which bogies on opposite sides ofthe vehicle may be rigidi connected together or adjacent bogies at eacside of the vehicle may be flexibly connected together. More than Aonerope is usually emplo ed, pulleys to carry them being arrangeaccordingly.

The drawings illustrate apparatus made in accordance with thisinventlon.

Figure 1 is a side elevation and Fig-l2 1s a transverse section. Fig. 3is a side elevation and Fi 4 is an end elevation Apartly.

in section o the same apparatus, bot to a larger scale. Figs. 5 and 6are a side elevatlon and a plan of a vehicle in which the bogies onoplosite sides are connected -to- 1g. 7 f'is an end view.

Vicarage, Becken-v In Figs. 1 to 4, a number of bogies 10 have two axles101 on which are wheels 102 running on an endless track 15 and on eachbogie 10 are two double pulle s 103 and on the vehicle are two sets ofpu leys 12, ropes 13 beingecured to the vehicle at 131 and 132 passingover the pulleys 103 and under the pulleys 12. The bogles 10 areconnected together by ropes 16 both ends of which are secured to thevehicle by means of springs, 161 and 162 respectively. The bogies 10float sidew'ise on the ropes between the pulleys 12 and the arrangementpermits of steering without skidding that portion of the track incontact with the ground and bearing the weight of the vehicle.

In Figs. 5, 6 and 7, the boges 10 are arranged in a similar manner tothose in Figs. 3 and 4 opposite bogies being connected together byshafts 17. One suspension rope 13 is required which is endless passingaround pulleys 18 at the ends of the vehicles while at the rear end therope passes around other pulleys 19 at the end of an arm 191 (see Fig.7) whose movement is controlled by a spring 192. The endless tracks 15are driven by wheels 21 and pass under the wheels 2O on the vehicle, andpivoted arms 22 having rollers 221 on one end bear against the tracks 15to take up any slack under influence of springs 222 at the other end ofthe arms.`

What I claim is 1. A vehicle body having supports beneath it, equippedwith pulleys mountedon said dy and supports to turn about horizontalaxes, and a rope connected with the vehicle body and passing over andiunder the pulleys to yieldingly sustain the vehicle body on saidsupports.

2. `A vehicle body having supports beneath it, equipped with a set ofpulleys mounted on the body to turn about horizontal axes and anotherset of pulleys mounted on the supports to turn about hori-` zontal axes,anda rope connected to the.

vehicle body and passlng over and under lt)l(1)e pulleys to yieldinglysustain the vehlcle 3.yA vehicle combined with a plurality of ulleysarranged at intervals along the lbwer portion of the vehicle, aplurality of other pulleys on the vehicle supports arranged alternatelyto the first set and a rope passing under the pulleys of one plurality nassenso and over the pulleys of the other plurality alternatel 4. Avehicle combined with a plurality oi ulleys arran ed at intervals alongthe veicle, a plura ityl of other pulleys arranged alternately to t e r:set and carried on bogies running on an endless track anda ro e passingunder the pulleys of one plurality and over the pulleys lof the otherplurality alternately.

5. A vehicle combined with a plurality of pulleys arran ed at intervals,dong the vehicle, a plura ityl of other pulleys arranged alternatelytot e first set and carried. on bogies runningon an endless track2 allexlble connection between adjacent bogles and a rope passing under thepulleys of one plurality and over the pulleys of the otheL pluralityalternatel 6. A vehicle comgined with a plurality of tplulleys arran edat intervals along the veicle, a plura it of other pulleys arrangedalternately to t e first set and carried on bogies running on an endlesstrack, a Hexible connection between adjacent bogies, a rigid connectionbetween boges on opposite si es of the vehicle, and a rope passing underthe pulleys of one plurality and over the pulleys of the other pluralityalternately.

l In testimony that I claim the foregoing as my invention I have signedmy name this 23rd day of Apfril, 1919.

PHILIP HENRY JOHNSON.
